Filed: 1965-07-08
Abstract: 1,130,294. Continuous casting; cutting by fusion. MESSER GRIESHEIM G.m.b.H. 8 July, 1966 [8 July, 1965], No. 29073/65. Headings B3F and B3V. To avoid local cooling of a continuous casting through contact with supports in the cutting region of a casting plant, the supports are moved in the same direction as but at a different speed from the casting. The supports may be rollers of a moving portion of a roller table for bearing the casting while it is severed by a flame cutter travelling synchronously with the casting. The table portion moves with the casting so that the flame cutter is always between two rollers of the moving portion to prevent roller damage. It travels more slowly or faster than the casting or it may be slower over the first half of the cutting region and faster over the second half so that the sum of the relative speeds is zero.

Title: Blasting initiator
IPC: F42B3/103
Filed: 1949-11-14
Abstract: 664,583. Blasting fuzes. DU PONT DE NEMOURS & CO., E. 1. Nov. 14, 1949. [June 11, 1949] No. 29095/49. Class 9 (i). An electric blasting cap comprises a shell closed by a rubberlike holding the leg wires, the plug being made of a composition containing sufficient carbon black for the electrical resistivity of the plug to be not more than 3 x 10<SP>4</SP> ohms per c.c. The metal shell 1 contains a base charge 2 of compressed tetryl with a primer charge 3 of compressed lead azide within a cavity in the charge 2. An ignition charge 8 of lead styphnate mixed with smokeless powder in proportion 80-20 and grained with gum arabic is superposed on the primer charge. The shell is closed by a plug 4 moulded about leg-wires 5 connected by a resistance wire 7 so that on passing a current through the wire 5 the charge 8 is ignited. The leg-wires are free from insulation for a part of the length 6 within the plug, which is a polymerised chloroprene composition containing 75 parts by weight of carbon black per 100 parts of neoprene. This composition is of sufficiently low conductivity to allow the firing current to pass through the bridge wire while the conductivity is sufficient for static discharges of the order of 10,000 volts at 0.0003 mfd capacity to be grounded to the shell. In a modification the loose ignition charge may be replaced by a bead 9 of lead styphnate surrounding the bridge wire. In this case the plug has a carbon black content of 75 parts per 100 parts of rubber to increase the conductivity. In another initiation the base charge 2 is a 50-25-25 blend of smokeless powder, a double salt of lead nitrate with a lead salt of dinitro-orthocresol and potassium chlorate. The primer charge is red lead and boron. The plug comprises 50 parts by weight of carbon black with 100 parts of rubber. As additional protection against static discharge a body of dielectric material may be placed between the exposed portion of the leg and bridge wires and the shell wall. Fig. 4 shows a sleeve 11 of dielectric material extending from a wedge-shaped extension of the plug. The dielectric material may be a solid mass almost completely enclosing the ignition bead and exposed leg wires or it may be used as a coating on the exposed leg wires and exposed part of the bridge wire. The dielectric material may be a synthetic resin composition or a sulphur-base cement. Synthetic or natural rubbers may be used for the plug and the carbon black content is preferably between 30 and 100 parts. The carbon black may be acetylene black.

Title: Aerial bombs
IPC: F42C9/06
Filed: 1939-11-03
Abstract: 577,130. Aerial bombs. DOBREMYSL, J. Nov. 3, 1939, No. 29274. [Classes 9 (i) and 9 (ii)] Relates to bombs suspended by parachutes for providing protection against enemy aircraft of the kind in which the bomb is armed by the tension in the suspension means. According to the invention, the safety device, rendering the bomb " live " only after launching, locks the firing member of the bomb permanently in the inoperative position after the pull on the suspension has once been relaxed. In the form shown in Fig. 1, the bomb 1 with its parachute 4 is mounted in a sleeve 2 which acts as a cartridge case or barrel for projecting the bomb from aircraft as described in Specification 577,131. The sleeve contains a propellant charge 3. The firing pin 7 of the fuze and the parachute are retained by a spring-urged lever 14 automatically released when the bomb leaves the sleeve. When the bomb is suspended, the piston 5 is pulled out against the pressure of a spring 6 and releases the upper end of a pendulum lever 9 movable in the firing pin, the lower end engaging a fixed bar 10. When the bomb is impacted by enemy aircraft the lever 9 swings away from the bar 10 and the firing pin is then moved by its spring 8 to fire the detonating cap 11 for the explosive charge 30. The bomb is rendered harmless, when the bomb reaches the ground and the suspension pull relaxes, by the return of the piston 5 which is locked in safe position by a radial spring bolt 18. This bolt before arming rests against a ring 16 which rises with the piston and is retained in raised position by inward movement of the bolt which on return of the piston can move still further inwards to lock the piston. In a modification, not shown, the lever 14 has an extension engaging the pistonrod of a spring-pressed piston moving in a liquid cylinder. The liquid used may be inflammable. The piston-rod is moved after a predetermined time to a position for locking the firing pin. In a further modification, Fig. 7, the pendulum control is replaced by a tail rod x on the piston 32 which controls the movement of balls 35 locking a firing pin 37 which acts by momentum on impact.

Abstract: A hydrocarbon-substituted thiophosphorus compound is obtained by reacting a thiophosphorus halide with an organic aluminium compound of the general formula Al(R)aX3- a in which R is a hydrocarbon group, e.g. a saturated or unsaturated aliphatic hydrocarbon group, a cycloalkyl group, an aralkyl group, or an aryl group, X is halogen, e.g. Cl, Br, F or I and a is 1, 2 or 3.  The thiophosphorus halide is suitably one having the general formula YiP(S)X3- b wherein X is a halogen atom, b is 0, 1 or 2, Y is R, -NR2, -R1-P(S)Xc(NR2)2- c or -O-P(S)Xc(NR2)2- c where R1 is a hydrocarbon radical having not more than 8 carbon atoms, X and R are as defined above and c is 1 or 2. The reaction may be carried out in the presence or absence of an inert organic solvent, and moisture and oxygen are preferably excluded from the reaction mixture, the reaction being conveniently effected in an inert atmosphere, e.g. of nitrogen or carbon dioxide, the latter being suitable when the aluminium compounds used contain less than 3 hydrocarbon radicals as in R2AlK and RAlX2.  If desired heating may be applied and this should not normally exceed 300 DEG C. Specified inert solvents are hexane, octane, an excess of an ether, e.g. diethyl ether or diisopropyl or di-n-butyl ether or of an amine, e.g. triethylamine, dimethylcyclohexylamine or pyridine and these may also serve as complexing agents.  The product may be recovered by mixing the reaction mixture with ice water, separating the resulting aqueous and organic layers and distilling the latter under vacuum. The reaction may be carried out by individual steps batchwise when more than one halogen of the phosphorus compound has to be exchanged and complexing agents such as alkali metal - chlorides - fluorides or - alcoholates or ether or amines may be present.

Title: Improvements in or relating to the catalytic conversion of hydrocarbon oils and apparatus therefor
IPC: B01J8/26
Filed: 1950-12-05
Abstract: <PICT:0693589/III/1> In apparatus for the catalytic treatment of hydrocarbon oils using a fluidized catalyst circulating between a catalyst hopper 11, catalyst regenerator 16, reactor 1 and catalyst stripper 10 the arrangement is such that the catalyst travels downwards in dense phase from the hopper to the regenerator and from the regenerator to the reactor, and upwards in disperse phase in the stripper from the reactor to the catalyst hopper.  The reactor operates under a pressure, e.g. of 0.91 kg./cm.2 in the disengaging space above the catalyst level 3, which as shown is about 9-15 metres above the reactor bottom, the catalyst density in the reactor being about 0.67 kg./litre.  Cyclones 4 are provided in the disengaging space and catalyst is withdrawn via a skirt or baffle 5 extending about half-way up the reactor.  Valves 9 control the flow of catalyst to the stripper where it is picked up by an upwardly directed stream of stripping gas, e.g. steam, and carried up as a disperse phase to the separating and collecting hopper 11.  Additional fluidizing means may be introduced at 19.  Air may also be injected into the stripping zone to increase the temperature therein.  The pressure is about 1.34 kg./cm.2 at the base and 9.05 kg./cm.2 at the top of the stripper which is about 26 metres long, so that the pressure in the stripper is generally lower than in the reactor. The hopper 11 has a cyclone separator 14 and operates at a pressure of 0.84 kg./cm.2 in the disengaging space. Stripped hydrocarbons and steam are withdrawn at 15.  Stripped catalyst flows to the regenerator 16 at a density of about 0.56 kg./cm.2 to the regenerator which operates at about 590 DEG C. From the regenerator catalyst flows in dense phase to a point near the bottom of reactor 1.  Oil is introduced into the reactor through jets 2.  In addition to cracking the Specification also refers to desulphurizing with bauxite as catalyst, refining, reforming, isoforming and viscosity breaking.
